This study investigates the moderating effect of meter penetration on the relationship between commercial losses and the financial performance of electricity distribution companies (DISCOs) in Nigeria. The Nigerian electricity sector faces significant challenges due to high commercial losses, including electricity theft, inaccurate billing, and poor revenue collection mechanisms, which contribute to financial instability. These issues are exacerbated by low meter penetration, with millions of consumers still receiving estimated bills, leading to disputes and revenue loss. The study adopts an ex-post facto research design, focusing on all 11 DISCOs operating in Nigeria as of 2024, using a census sampling technique for comprehensive data collection. Both quantitative and qualitative data are gathered, including secondary data from DISCOs’ annual reports, financial statements, and regulatory filings from bodies like the Nigerian Electricity Regulatory Commission (NERC). Data analysis includes descriptive statistics, correlation analysis, and multiple regression to assess the relationship between commercial losses, meter penetration, and financial performance, particularly focusing on the moderating effect of meter penetration. The findings show that commercial losses significantly affect DISCOs’ financial performance, confirming that addressing these losses is crucial for improving financial stability. Furthermore, meter penetration was found to significantly moderate the relationship between commercial losses and financial performance, suggesting that higher meter coverage can alleviate the financial burden of these losses. The study concludes that while increasing meter penetration is essential, it must be accompanied by effective enforcement and operational reforms to maximize financial benefits. The results offer important insights for policymakers, regulators, and industry stakeholders in Nigeria, providing actionable recommendations for reducing commercial losses and enhancing the financial sustainability of DISCOs.
